The measure was approved 96-52 on Thursday, and it now goes to the Senate. If approved by the Legislature, the amendment could appear on the November ballot.

The proposal would bar state restrictions that impose an “undue” financial burden on farmers. It also would require farming laws to be based on “scientific principles.” Initiative petitions dealing with livestock or crop-raising would be banned.

Sponsoring House member Tom Loehner, a Republican from Koelztown, says the changes are needed to protect food production. But critics contend the proposed amendment is poorly worded and could create problems.
